Patented Jan. 5, 1932 UNITED, STATES PATENT OFFICE' JOHN S. NORTON, 0FSAN FRANCISCO, CALIFORNIA, ASSIGNOR 0F ONE-THIRD TO 'WIL- LIAM F.HOLLINGSWORTH, OF SAN FRANCISCO, CALIFORNIA WELDEBS HOOD Application medAugust 18, 1930. Serial No. 476,188.

The present invention relates to improvements in a welders hood, and itsprincipal object is to provide 'a convenient means or operating the lensof the hood so that the Welder when desiring to view the Work ma raisethe lens without the use of his han and without changing his position.

More particularly it is proposed in the present invention to use apressure means or operating the lens and to arrange the pressure meansin such a manner that the same may be actuated by a bulb arranged to liein the arm p-it of a person wearing the hood so that the lens may beraised by squeezin the upper arm against the body.

It is further proposed in the present invention to use a hood made ofleather or fabric or flexible -composition and to arrange the operatingmeans in such a manner as to allow of free access of air into the hoodand to give as much comfort to the operator as 1s possible.

Further objects and advantages of my invention will appear as thespecification proceeds.

The preferred form of my invention is illustrated in the accompanyingdrawings, in which Figure 1 shows my hood on a Welder;

Figure 2 shows a rear view of the fro-nt section of the hood includingthe principal parts of my operating mechanism;

Figure 3 a vertical section taken along line 3-3 of Figure 2, and

Figure 4 a horizontal section taken along line 4-4 of Figure 2.

While I have shown only the preferred form of my invention, I .wish'tohave it understood that various changes or modifications may be madewithin the sco e of the claims hereto attached without eparting from thespirit of the invention.

In its preferred form my hood indicated at 1 is preferably made ofleather or flexible composition of suitable kind, and has a frame 2 madeof metal provided in the front portion thereof. yThis frame for which asuitable openin is made in the hood material is fastene to the marginalportion of the latter by an inner frame 3, the margin of The frameitself has mounted over its vopening a hinge 5 to which is pivoted thelens frame 6. The lens frame carries an inner lens 7 of eye protectingproperties, held in place by means of springs 8 and an outer lens 9 ofordinary glass held in place by two guide members 10 and bottom members11.

One of the edges of the lens has an arm 12 extending rearwardlytherefrom, and the outerend of this arm is connected by means of a link13 to a piston Irod 14 extending from a piston 15, which latter isreciprocable in a cylinder 16 mounted adjacent the lens opening. Thepiston rod passes through a Vguide plate 17, and a spring 18 surroundingthe piston rod and bearing on the guide plate has a tendency to push thepiston upward in the cylinder. The upper end of the cylinder has a s ortpipe 19 extending therefrom, and this ipe connects with a flexible tube20, having a ulb 21 at its outer end so that by compression of the bulbair is forced into the cylinder, and urges 'the piston 15 outward,whereby through the action of the link 13 and the arm 12, the lens isthrown upward into the dotted line position shown in Fi re 3. The tube20 is preferably made su 'ciently long that it can be guided around theback of a person as shown in Figure 1, and allow the bulb 21 to be heldin one of the'arm pits, and to be compressed by a slight movement of theupper arm. y For the convenience of the operator a spring clamp 22 maybe fastened to the bulb whereby the latter may be secured to the upperarm of the individual using the devlce.

Above the lens, I preferably fasten a spacing member 23 consisting of afairly wide strip of spring metal having a central por,- tion 24corresponding to the outline of the meansof which it may .be fastened tothe top of the frame. `A suitable elastic 26 fastened to the two ends ofthe member 24 may be guided around the head for holding the metal 'humanforehead, and having two legs 25 by portion of the hood in positionrelative to the forehead.

The advantages of my invention will be readily understood from theforegoing description. The hood made of exible material maybe moreeasily carried and accommodated in smaller space than the hood made ofrigid material. It is particularly adapted for overhead work and forwork in tight places. The operating means for the lens is particularlyeffective and easily operated. The bulb being fastened to the upper arm,does not interfere with any of the other operations of the Welder, andwhenever it becomes necessary for the latter to raise the lens so as tohave an opportunity to inspect the work, he need only press his forearmagainst his body, which will cause the lens to swing upward on the hinge5. If he swings the lens far enough the arm 12 and the link 13 becomepractically aligned for holding the lens in wide open position. Undernormal conditions the spring 18 automatically returns the lens, and theother movable parts into proper position as soon as the pressure isrelieved.

I claim:

l. A welders hood of the character described having a movable lens,pressure operT ated means for actuating the same, a bulb and a flexibletube connecting the bulb and the said means, the exible tube beingsuiciently long to allow the bulb to be positioned in the arm pit of aperson wearing the hood and to be compressed by a movement of theWelders arm, and means for fastening the bulb in place.

2. A Welders hood of the character described having a movable lens,pressure actu- .ated means for actuating the lens, a bulb having a limbencircling member secured thereto adapted to embrace a limb of theWelder and allowing the bulb to be compresse-d by a movement of thelimb, and a flexible tube connecting the bulb with the pressure actu'-JOHN S.
